Abstract: Compelling scene movements in a virtual reality (VR) system can cause symptoms of motion sickness (i.e., cybersickness). A study has been conducted to investigate the effects of scene oscillations in different axes on the level of cybersickness. Sixteen male were exposed to four 20-minute VR simulation sessions with at least seven-day separation between consecutive exposures. The four sessions used the same virtual environment with scene oscillations in different axes: pitch, yaw, roll and no oscillation (speed: 30°/s, range: +/-60°). Verbal ratings of nausea level were taken at 5-minute intervals and sickness symptoms were measured before and after the exposure using the Simulator Sickness Questionnaire (SSQ). Significant differences were found between the no oscillation condition and the oscillating conditions. With scene oscillation, nausea ratings increased significantly with exposure duration for all the axes of oscillation. Scene oscillations in different axes did not significantly affect the nausea rating and the SSQ scores. The main effects and their interactions are discussed in the paper.
